“Prove BESS economics. Stop guessing.”

Where it wins

• Deterministic, auditable optimization replaces black-box AI with traceable LP/MILP solvers for investment committees [1].
• Unified modeling of FCR, aFRR, DA, and EEG revenue stacks in a single platform, eliminating fragmented spreadsheets [1].
• High-resolution 15-minute dispatch simulation with real degradation curves and cell chemistry parameters for accurate NPV/IRR [1].

Credibility: phelas.com (Catalyst product page), European market templates (DE, FR, ES, IT, PL, NL, AT, BE, IE).

SaaS platform for deterministic BESS project evaluation, scaling via cloud-based simulations [1]., Unit of value: NPV/IRR accuracy and investment committee readiness through explainable outputs [1]., Margin sits in software delivery vs. manual spreadsheet modeling, with high switching costs due to data integration [1]., Templates and market-specific modules drive adoption across EU markets [1].

Spreadsheet-based models: fragmented, error-prone, lack real-time market data [1]., Black-box AI tools: untraceable, unsuitable for investment committee scrutiny [1]., Specialized BESS software: often limited to single revenue streams or markets [1]., Differentiators: Deterministic solver, unified EU market coverage, and investment-ready outputs [1]., Threats: Entry of major energy software providers (e.g., ABB, Siemens) with broader portfolios [1].

Hybrid PV/wind + BESS projects lack robust evaluation tools, leading to missed opportunities [1]., Investment committees reject projects due to unexplainable black-box AI or fragmented spreadsheets [1]., Manual modeling fails to capture high-resolution dispatch and real degradation effects [1]., European market complexity (FCR, aFRR, EEG) requires specialized, localized expertise [1].

Catalyst’s wedge is explainability for investment committees, critical as hybrid projects scale. Main risk is data licensing costs and regulatory changes in EU markets. Opportunity lies in expanding to non-EU markets and adding grid constraint modeling. Next signal: Adoption by top 5 European IPPs would validate the model.
